CLARENCE RATHBONE, OF ALBANY, NEV YORK.

VENTILATING ATTACHMENT FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 367,445, dated August 2, 1887.

(No model.)

To all whom, it may concern:

Be it known that 1', CLARENCE RATHBONE, of the city and county of Albany, in the State of New York, have invented new and useful Improvements in VentilatingAttachments for Stoves, of which the following is a specification.

My invention relates to improvements in attachmen ts to stoves for carrying off the vitiated air from the room in which the stove is used; and it consists in providing one of the outer walls of the stove with a small air-inlet opening leading into and delivering its air directly into one of the draft-fines of the stove, the said air-inlet being provided with an inner air-channel having a metallic screen or screens by which the entering air is divided into mi nute streams and warmed before entering the stove.

In the accompanying drawings, which are herein referred to and form part of this specification, Figure 1 is a rear elevation of aheating-stove provided with my invention; Fig. 2, a vertical section of the same; and Figs. 3 and 4 are a rear elevation and a verticel section of a modification of my invention.

As represented in the drawings, A is the body of the stove; a,a draft-flue leading from the fire-chamber to the smokeoutlet B; G, the inlet air-opening, of from one to two. inchesin diameter, that is formed in one of the outer walls of the stove, and leading directly into the draft-flue a, as shown in Figs. 1 and 2.

The inlet airopening O is left open, and a short channel-piece or pipe, D, is fixed to the inner side of the plate to form a continuation of said inlet air-opening, that will conduct the air admitted through the opening 0 in a direction corresponding to that of the draftcurrents in passing through the flue a. The

heated draft-currents impinge against the screen 0, and thereby heat the metallic body of said screen, so that the minute currents of air which pass through said screen will become heated to such a degree that they will not chill or check the heated draft-currents in their passage through the line a.

The modification shown in Figs. 3 and 4 differs from the one last described by having a screen, 0, fixed over the opening 0 in addition to the screen 0, fixed over the inner end of the channel-piece D. This construction, besides giving an additional warmth to the ingoing air, prevents the entrance of any dust from the room into the opening 0. Instead of forming the inlet airopening O to lead into an ascending draft-flue, as shown in the drawings, said opening may be made into either a horizontal or descending fine, that communicates with the smokcoutlet of a stove; and my invention is equally applicable to a cooking stove, range, or any other class of stoves or heaters as to the stove shown in the drawings.

I am aware that stoves with ventilating attachments have heretofore been made; but in those earlier devices the ventilating -pipes were without screens for dividing the air into minute currents, and said pipes were made of great length for the avowed purpose of permitting the air passing through them to become thoroughly heated before escaping through the smoke-outlet of the stove. I do not claim such a construction; but

I claim as my invention- The combination, with a stove and its contained draft-fines, of an inlet air opening formed in an outer wall of the stove, and its connected inner air-channel having an aperture covered by a metallic screen, the said airchannel having itsdelivery-opening within one of the draftilues of the stove, as herein specified.
